Qemu crashes when running kvm-20/21 as module in kernel 2.6.21

Hi,

First I tried kvm build into the kernel, 2.6.21, togeather with kvm-17, no problem at all, except that qemu shuts down when I do a reboot in the guest os. Is there any fix for that btw, guest os is Linux Slackware 11.0 with kernel 2.6.21?

After that I tried upgrading to kvm-21, removing kvm from the kernel. Now qemu crashes on startup, but works if I use the -no-kvm switch, also tried kvm-20 with same problem. I get no error when I load the modules so I assume they load just fine.

lsmod:

That's a known problem. A fix will be available eventually, but it will take some time.

If the image is not too huge, and if it contains no private information, can you post it somewhere for me to download? I'll have a look.

I was a bit quick and deleted it. Forgot to mention that the disk image at some point magically got converted to raw format, from cow. Maybe it got corrupted when I convert it to qcow2 or by qemu itself.

This makes sence since if you try to boot qemu with a empty disk image you get the same crash.
